Needed to put air in left front tire. Went to usual gas station. Went to usual air pump. Took cap off tire. Put quarters in air pump. Quickly picked up hose. Little water leaked out. "Rain." Inserted hose into...blowup part of tire. Watched tire rise slightly off ground. Removed air hose. Water gushed out of hose. Noticed other hose. Checked: air came out. Wondered what putting water into a tire could do. Had anxiety attack. Mild.
